ckeck engine light on

[AtomicPunk]

Update: Code came back. Playing Canadian Tire/Mitsubishi Dealer mechanic was a failure. I should tell the guy that now there's a new problem that's totally different from the last time but that's not the case.

There's p0171,p0102 in the ecm then C1396, and U0401 stored in the abs module. The car runs like the pooh once in a while and the abs/trac control lights come on at the same time. Driver said it was sluggish. They also said when they fill up with fuel it takes a while for it to start after. That part sounds weird to me. I'm now thinking fuel pressure issue now. I'll have to make an adapter from a damaged fuel rail to test under the hood or just replace the pump with one of the next to no miles used ones I have around here.
I'm assuming the abs codes are possibly being caused by the engine running like crap.

Might as well change the spark plugs again too. It's been 200k kms/124k miles since they were last changed.

Just spitballin' here, but what about a bad wheel sensor? Sending bad data to the abs/traction control module, and the ecm is then adjusting the engine/cvt for what it thinks is a slipping wheel issue?
